Body Quote by Aristotle
“For any two portions of fire, small or great, will exhibit the same ratio of solid to void; but the upward movement of the greater is quicker than that of the less, just as the downward movement of a mass of gold or lead, or of any other body endowed with weight, is quicker in proportion to its size.”
About This Quote
Source Treat: Physics, Book III, Aristotle, 4th century BC
Solid and void maintain a constant proportion in fire, but larger masses rise or fall faster due to weight.
In simple terms: Larger things move quicker because of weight.

A Different Perspective
Larger objects may encounter resistance not captured by simple ratios.
![“I've used the Phoenix Centrifuge to replicate what the body's going to go through on the flight up. I've also done some gravity tests with ZERO-G [a charter-flight service in Arlington, Va., that uses modified Boeing 727s to simulate weightlessness], which went great.” quote by Richard Branson](https://sms4smile.com/quotes/img-quotes/aa1/richard-branson-256_adventure_i-ve-used-the-phoenix-centrifuge-to-repl_903.jpg)
